After updating to php 8.0, the menu no longer works.
Instead of the called category blog an error page is displayed:
0 count(): Argument #1 ($value) must be of type Countable|array, string given
I also get the following error messages:
PHP deprecated: Required parameter $pos follows optional parameter $pid in /mnt/web304/d3/24/5345024/htdocs/templates/gk_events/lib/menu/GKMenu.php on line 66

Would you please help me to fix this.
Thanks in advance
